' Application filed February 23, 1927. Serial No. 170,104.

My invention relates to blow-torches and particularly to a tinning cup attachment for the same. i v

The primary object of this invention is to provide a device which is especially adapted for electric linemen in soldering or tinn'ing connecting wires-as for example the wires of outlet boxes-or other like purposes.

The invention consists in a simple, inexpensive supporting bracket and cup'which may be secured to any of, the usual type or" blow-torches, the construction being such that V the solder cup may be readily removed or replaced as required,the arrangement however is such that the flame may be projected constantly against the wall of the cup to maintain the solder in molten condition to receive thev ends of the wires or other elements to be soldered together,-it being only necessary for the workman to arrange the ends of the wires or other parts in adjacent relation before submerging the same in the cup containing themolten metal to tin or solder the parts together.

' The device further provides for the removal of the cup from the supporting bracket whereuponthe blow-torch may be employed in the usual manner without removing the cup supporting bracket. V

By providing a divided cup supporting braket. the bracket elements may be readily clamped upon the mixing chamber of the valve fitting secured pipe, the construction of the bracket being such that the clamping screws extend through ears projecting from each bracket member tosecure the bracket in position and are so disposed that they will not become overheated or cause the bolts to loosen or be destroyed.

A further object of the invention consists in constructing the melting cup with a tapering inner wall that the metal which may be allowed to cool in the cup will not'tracture the latter due to expansiontherein.

With the foregoing and other objects in view which will appear as the description proceeds, theinvention further resides in the combination and arrangement of parts and in v the details of construction hereinafter described and claimed, it being understood that changes may be made in the precise embodiment of the invention herein disclosed with out departing tromthe spirit of the same.

to the end of the fuel.

In the drawings accompanying this specifi cation:

Figure 11s a side elevation of a blow-torch of usual construction showing a divided annular clamping bracket fitting embracing the mixing chamber of the valve and inclosing the gas flame,the melting cup being supported'in the bracket fitting- Persist times,

, Figure 2 is a fragmentary end elevation of the fuel pipe leading to the valve fitting showing the divided annular bracket and the melt" ing cup supported between the walls of the bracket.

Figure '3 is a cross-sectional view throughthe divided annular bracket taken on or about line 33 of Figure 1showing the bolts engaging the pro ecting ears of the bracket to clamp the parts to the valve fitting.

Figure 4 is a vertical cross-sectional view through the melting cup.

Referring now to the letters of reference placed upon the drawings: 7

A denotes the fuel chamber of a gasoline blow-torch of usual construction. B indicates a supporting handle which also serves as the cylinder for the usual compression pump, and C denotes a knob on the endot the plunger rod for operating the pump. 1) is a pipe leading upwardly from the fuel chamber to a 'valve fitting E, from which is suspended a priming cup F of usual construction. G and H are needle control valves. 1 indicates an annular divided bracket member, each part respectively provided with projecting ears J, whichregister in opposing relation when the parts are assembledto embrace the wall of the mixing chamber L,-the connecting bolts I K securing'the walls ot the divided brackets together to embrace the wall of said chamber. M is a melting cup Supported by and between the walls 01"- the divided annular bracket in position toreceive the flame of, the torch. The

inner wall of the cup is tapered that the metal may be allowed to cool in the cup without danger of :lracturing its walls.

Having indicated the several parts by reference letters, theconstruction and operation of the device will be readily understood. As previously explained. when it is desired toztin or solder wires or work of like character, it is only necessary to bring the parts into adjacent relation, bending the ends downwardly so that the cup maybe raised to submerge the wires oreother elements in the molten metal therein,the parts are thus soldered or tinned without furthermanipulntion, 5 Having thus described my invention What I claim is: a i

' A tinning cup attachment for a torch comprising a tubular bracket, said bracket havngopposite end portions axially alined with 10 each other and of different internal diameters, means for attaching the end port-idn of lesser diameter to the torch, and the end portion of greater diameter having means for supporting the cup transversely of the axis of the bracket With the exterior surface of the cup spaced from the inner surface of the bracket. 1

In testimony whereof I sign this specification. 7
